Failed to import pool 'rpool'. on first boot Proxmox 5.0 zfs install

[ndroftheline]

Hey crew,

Struggling to get Proxmox 5.0 on one of my test bed hosts. I had a 4.4 install on this humming along but then fubar'ed it by playing too casually with trying to cluster with a machine in another country. Wups.

On boot it shows some typical boot messages I was getting on 4.4 (scsi 2:0:32:0: Wrong diagnostic page; asked for 7 got 0) and then the messages in the screenshot. I'm sorry I can't copy/paste from this older server's iDRAC implementation (Java ftw):

In case it matters, it's a Dell R610, dual procs, 72gb ram, 6x 600gb 10k drives, with a Perc 6/i controller in it. This is a test node for now so I'm doing dumb things like storing a ZFS RAID0 on a hardware RAID0 I've set up in the controller.

This setup worked fine in Proxmox 4.4.

zpool list says "no pools available". Next steps?

you have two rpools on the disks seen in the initramfs, so it does not know which one to import. run "zpool import" to see which disks get detected in which pool. you can then import one of them using a different name, export it again and reboot.

cool, thanks heaps fabian. that did the trick. i got a bunch of errors about being unable to umount certain directories, but after a forced reboot the node seems to be behaving. now to figure out how zpool imports work so i can dissect the old pool.
